I work with medical software. Every program is proprietary win98-tier mess. They were clearly programmed by turning electronic health software standards into feature checklists; they saw "daily backup" and made a .bat file that copies mysql's entire directory to some other place on the same computer. It's the kind of mess that you could improve upon by copy-pasting from stackoverflow. It's that bad.

There's also software that interfaces with the gigantic medical machines like computerized tomography or magnetic resonance imaging machines. Nobody is madman enough to reverse-engineer that shit. Due to the sheer money involved they tend to be better, but they're still borderline unusable windows crap... Radiologists are making too much money to care though. Since they're fuckhuge appliances they could easily fix all these problems by recording all data in volatile internal memory and allow interfacing and transfer via a web browser, or even a HTTP API electronic health record systems could make use of to drive the machine and import imaging data directly into the patient's record.

That's what (-1)^n is for. For even values of n (-1)^n == 1, otherwise it is -1. All you need to do is to increment n for each level of recursion.

Hi,

Still working on my alarm clock. Im almost done adding the TTS portion, but I am stuck.

For user created functions, how do you decide what to import and what to just keep on the main file?

I feel like I could have my main file be 3 lines of code made up of functions inside functions inside functions.

Or it could be 1000 lines with only built in libraries being imported.

What are the PROS AND CONS.

thanks a bunch.

unsigned char sleeve[] = {
    0xaa,0xad,0xfd, 0xe9
};
unsigned rotr(unsigned x, unsigned n) {
    return (x >> n % 32) | (x << (32-n) % 32);
}
char* dumb(char* input, int size) {
    char *state = malloc(32);
    memset(state, 0, 32);
    memcpy(state, input, size);
    for(int i = 0; i < 9; i++){
        for(int k = 0; k < 32; k++) {
            state[k] ^= (rotr(state[31 - k],3) ^ sleeve[k/8]);
            //state[31 - k] %= 4;
        }

    }
    return state;
}

>>61975079
>Still working on my alarm clock
what alarm clock?

One thing i'm thinking about implementing in my language is returning function names as short-hand versions.

function is 
      //declarations go here
<=
      //statements go here
=>func

func

But, i don't know, maybe that'll make the compiler have to do too much back tracking. Personally, i like having short function names, but I also know it's a pain in the ass for anyone who has to clean up my mess afterwards.

Why does my makefile detecting changes to my main.cpp file even when all I change is a single character, but not when I change a single character in my class files? How do I get around this without having to use a make clean all the time?

>Gonna be honest, I won't touch any version of Java

sometimes i think tripfags make posts they don't actually even want to make, just because they feel obligated to post

>>61975079
think in terms of boxes. Lets say you want to tidy up your room. You would probably put things you want away, like shoes, shirts, magazines, CD's, etc. However, you would also want to be able to find them again, so you'd put those things in the same area (shoes go in a box, shirts go in drawer with socks and pants, etc.) You can do the same with your functions, putting similar things in similar files.

>>61975181
you sound inexperienced with make, so it's probably doing what you're telling it to do in the makefile

>>61975181
is the class file listed as a dependency?

makfiles work like this:

file : depency1 dependancy2
commands

dependancy1 :
commands

dependancy2 :
commands

make looks at the first listed file in the makefile, in this case "file", and checks if it has been changed."file" is considered changed if either dependancy1 or 2 have changes in them as well as if "file" has changes

if only file has changes, only file's commands are ececuted
if dependancy1 has changes, it's commands are ran, then file's.

you can also have things like this

notactuallyafile :
run some commands

(activates only when "make notactuallyafile" is called from the command line

Sure it takes time and money to do so, but so does maintaining it.

>>61975191

It depends on what I'm doing. If I need to quickly process a bunch of data once, you bet your ass I'll write a Ruby script, and I'll get it done faster than had I used Java. If I need to write an application to be used by other people, I'll probably use C++. I'm more productive with it, and I can produce a better, faster application with it.

>>61975181

Since >>61975307 did a good job of explaining why your makefile doesn't rebuild when you change the header, I'll give a few ways to fix this:

1. Use the touch command on every file that includes the header so make will have to rebuild those.
2. Add the header as a dependency in the makefile
3. Just use cmake and let it handle your dependencies.

>>61975427
C++, D, Red

>>61975214
>>61975214
I think I got what my problem was: It's not that it didn't detect changes to them, it's that they didn't check for these files at all. All it checks are .cpp files, so if I modify my .hpp files it won't see any changes and will tell me it's up to date.

So I either split the classes into definition and implementation, no matter how tiny they are, or I make clean every time I make a change to the .hpp files. This is annoying.

It's just like you can teach a person to farm, but are you going to do the actual farming for them?

No, where the hell would you get that idea? To put things into perspective, most people would consider that working in a cafeteria is not in any way morally or ethically bad. At the same time, volunteering in a soup kitchen (literally doing the exact same thing for free) is also not morally or ethically bad. Yes, it's fine to make money off of your work, and you should if you can. But that doesn't mean you need to trash people who volunteer their time to a service that they think will benefit society.

>>61976585

I am not trying to get anyone to do work that they do not want to do. I am not telling people to make free software. I am telling you to shut the hell up with your complaints about people doing work for free. Just as you have a right to work in exchange for money, you have a right to work for free, motivated only by the goodness of your own heart. This kind of action is considered morally virtuous, and we should not shame others for doing so.

Writing free software != "Do this or I'll shoot you"

>>61977223
Is it any different though? Companies in places like SV often ask people for their Githubs, which could be tantamount to saying "write free software or there is a lower chance of you finding a job thus causing you economic difficulty".

>>61976948
>>61977210
Google is a private entity, and regardless of whatever PR they try to spin, their sole motive is to make as much dough as they can; if they fail to deliver, the market will provide opportunities for competitors. That is how economics work. People who think there is some grand political scheme at work are naive, and if they think Google was peachy keen as a company before the memo shitstorm, they are complete retards.

Permissive license users may be useful idiots at times, but if they want to use them, that's their choice. I'm not giving up on free software just because someone you despise may just so happen to use it one day for some reason or another.

>>61977274
>their sole motive is to make as much dough as they can
By brainwashing people and attempting to control reality? Everything Google does is outright dishonest in some way, the only reason they have gotten away with it is that people haven't wised up to what they are really doing.

Goddammit, I'm an atheist, but all of this anti-volunteering crap is making me want to throw a bible at someone.

>>61977326

I'm not against volunteering. However as with anything there should be a good reason for doing it.

>>61977363
Then why not quit your job, or better yet tell your employer you'll work for free? Surely you wouldn't want to be taking money from people for doing worthless things, right?

Well... yes. How is this not logical or intuitive? A profitable, ethical company is a pipe dream for retards that worship markets like gods.
The term "virtual signalling" exists for a reason. Companies very rarely believe a word of the pandering political tripe they say. It's no different from when they branded themselves as "patriotic" during the Cold War even though they were eager to do business with Soviet bloc nations that hadn't reverted to capitalism yet.

>>61977418
>Look at it like this: it stops the chicken and the egg problem of no experience, therefore can't get job, therefore no experience.

...or is it that the "no experience no job" meme was created to extort people into working for free? There are companies in places like that commie shithole China where one has to PAY to work just so they can get experience. I can tell pretty much just by looking at a person whether they are reasonably intelligent, I could not fathom why others would have a problem with this.

>In many cases, it's just... "I felt like it." Someone makes a program that suits their own needs, and it happens to benefit others. Or maybe it doesn't satisfy a need, it's just something to make when you're bored, or as practice for greater work.

>or is it that the "no experience no job" meme was created to extort people into working for free?
It's really a supply and demand issue. As people gain experience in the workforce, they become more desirable than people without experience, since they fuck up less and there's less cost to train them. So companies ask for people with experience. If people can gain experience in other ways, they do so. If they cannot, and there are not enough people on the market with experience, then companies will try to import foreign workers who have experience. Failing that, they will hire and train the less qualified employees. It's not really some meme that was created intentionally by some group. Rather, it's the natural result of businesses making the most rational move for their company, and the market adjusting accordingly.

>felt like it because of commie propaganda and brainwashing?
No. Believe it or not, many people actually enjoy programming as a hobby, not just as a job.

>>61977483

But that would create value out of the code, and you said that code doesn't have value.

>>61977729
Google often creates internal APIs that are very valuable to them, but then they open source them and make them free to use. The code creates value, but it isn't valuable itself as a commodity (it's completely free).

>>61977769
If code is not valuable then why should people bother making free software?

How do people survive without vim-like regexp replace?

How do you fix the feeling of your code/class structure being unmaintainable spaghetti that you can't build off of or modify? I'm wanting to make a little minecraft clone with OpenGL/C++ and I implemented the basic game loop, rendered a 3d cube with a camera and camera navigation, and implemented simple text rendering, and I am already feeling overwhelmed.

What causes this spaghetti feeling? I think it's because all the little subsystems of the game have to have references to eachother, so they're...co-dependent? It doesn't feel right but I also feel like most software has to be pretty tangled. Is this just OCD autism getting to me?

For example, my main Game class initializes and has ownership of a bunch of objects like Shaders and Textures and a TextRenderer. I have to pass a Shader to the TextRenderer, and my BitmapFonts have a method that returns a reference to the Texture that font corresponds to, which the TextRenderer will need. Does this sound like a normal class structure or is this fucked? I mean with OOP certain classes will have to have references to other ones and depend on them, right?

>>61978212
So you're the devil then, eh? You must think that is "sexy" or something. You're a million times worse than I ever thought.

>>61978237
You need to figure out how to make them not codependent. This is typically done in the OOP world with interfaces, and "seperation of concerns". A lot of complicated systems are designed in layers where each one extends only the one below it (e.g. compilers are built this way). You might have to do some thinking beforehand to figure out how to achieve good design. My biggest tip I can give is always be prepared to delete code.

This is fundamental in functional programming too. The only problem is that FP also encourages immutable data structures, which make a lot of sense as data, but tend to be slow for intensive things like games.

Atom with lots of comfy packages

>>61979261
This but you'll need filesystem-specific routines

>>61979261
Can't I just smack the write pointer 2 million bits ahead and write a digit?

>>61979253
Yeah, but you can modify it to do whatever you want. Maybe change the filename every iteration, or put a specific number of files in particular folders, etc

>>61979269
no you don't, fopen and fwrite are standard library functions

>>61979220
You should just create files, you don't need to write anything in them. The files will still be 4096k.
Also you should have some special characters in the name, it might confuse the shell if user wants to delete them from terminal.

>>61979279
To iterate through the filesystem, no? If I wanted to write an annoying worm that filled every folder you have with junk, for example?

>>61979289
you can use dirent.h on windows at least, the only issue arises when dealing with unicode filenames as windows uses UTF-16 so you'll need to use MS' wchar APIs there. if you stick to ANSI paths you'll be fine

Building out the back end plstform, database, client Android app, and admin webapp for a medical prototyping company. All by myself, trying to finish it before school starts up in a few weeks while working full time wanting to kill myself maintaining outdated military software built in flash. Yes, fucking flash. I tend to bite off more than I can chew but oh well. Springboot is a lifesaver though.

I need more, anon. Please

>construct
Is the default constructor called?

>>61979510
If one exists, yes

>>61979510
You can call placement new with arguments.

>>61979523
Is it good practice to leave the default constructor blank and never use the upper example?

Learning C++. I don't want to work as a web-monkey for my entire life (C# ASP .NET MVC dev)

i also know C more or less

>>61978619
Okay so in regard to that post, I'm trying to use this:

Double[] nums = Array.ConvertAll<string,double>(stringWithCSVs.Split(','), double.Parse);

But after I build the program, it crashes there. I've made 100% sure the string I am sending it is correct (checking chars until a /n arrives before I readline() to make sure no fucky bytes are read, and then printing the string into a textbox to double check the string) and still no love.

I am using Visual Studio 2005 (.Net 2.0) could that be the problem?

>>61979711
Oh and any fucky capitalization can be ignored, I'm phoneposting without my code in front of me

>>61979701
So what's your question lmao.

What music do you listen to while you kode???


If it's anime please don't even reply to this post. I don't want to even see it.

>>61979727

Nothing, just saying what i'm currently doing. Sadly i can't study C++ except for weekends, no time. I'm so tired after work that i can't even jack off.

Almost finished Lippman's book, enjoying Seepple for now, doesn't look that bad.

>>61979754
Why don't you just learn java? Seriously.

>>61979768

Are you kidding me? Java is a piece of fucking shit. I tried learning it before becoming C# dev and i vomited week after i started.

C# Is Java if it was good. I learned it in 4 months after C and started working in 6 months, lol.

>>61979801
C++ is just as fucking bad.

>>61979812

C++ is at least brainfuckingly fun. Java is pajeet tier, i can't handle it.

>>61979830

>>61979830
>brainfuckingly fun
You either suck at it or are actually autistic.

>>61979801
C# is just Java with tons of shit heaped on.

>>61979841

I'm autistic. I like C and system programming, i like C++ right not because i'm not far into it yet. Maybe it sucks later.

>>61979844

C# has a lot of useful syntax sugar compared to Java. It's better.

And not only syntax sugar. It's functionality is much wider.

>>61979857
>later
There's an exact point where C++ turns to dogshit, it's when you stop writing advanced C and begin following crazy senseless paradigms.

>>61979857
Most of the new functionality just reduces clarity.

>>61979863

Oh, i'm not planning to write pure "modern C++" code anon. But there are quite few useful functions and paradigms in C++ which i'd mix with pure C code.

Honestly, i'm just tired of reinventing bicycle in C sometimes. C++ can handle such situations.

>>61979873
Every new C++ feature added is to fix an old C++ feature.

>>61979863
I use C++ like C with classes. I write my own containers which internally use void * but are created with factory templates for the type-safety — other than that, I stay away from templates. I like RAII. I like having the built-in vtable if I want it.

>>61979877

Also i'm too stupid for using pointers withtout RAII and not fucking something up, i think.

Maybe not stupid but certainly i have concentration problems and low energy

>>61979899
All C++tards confirmed for being too stupid for C.

>>61979909

Maybe, anon. Maybe.

>>61979899
you just have low stamina. sad.

>>61979909
wtf is the point if you're not developing a kernel or some low level shit. Using C# for windows programs is simple and there's tons of dev tools to port your program to basically any modern OS.

>>61979909
Too unwise, yes. They are more than intelligent for taking 20 things into consideration at the same time.

Is this true?

>>>/v/387588080

>>61979929
No.

>>61979929

No. C will never die in nearest future.

That's cool.

Type erasure a la Java. There's probably a cooler way to do it but it works for me.

Everything he said is true except Sublime is a great editor

might try the new stack2nix on a project; as I was told this one is pretty good so hopefully can replace the internal version I wrote

Is it valid C to initliaise an array in a seperate function and return a pointer to the array, or will the full array be deleted as it was initialised as a local?

>>61980502
use malloc?

>>61980514
Don't heap allocate if you don't have to. Stack allocate an array then pass a pointer to the initialization function.

>>61980514

I'm just asking if it will be deleted or not, I've not got onto the stdlib functions yet.

>>61980518
Yes.

>>61980518
it'll be removed when it leaves scope.

do what >>61980516 is suggesting and allocate it in the caller and pass it to the callee via a pointer.
but if the callee is creating the object, then you have to malloc it to keep it alive after the stack frame changes
